Abstract:The interaction of rat cauda epididymal sperm cAMP-dependent protein kinase (PKA) with seminal vesicle fluid (SVF) proteins was examined. Specific proteins in SVF act as substrates for the sperm cell PKA. The apparent molecular weights of these proteins are 45.0, 31.5, 17.2, 14.7, and 13.3 kDa. The phosphorylation of one low-molecular-weight cauda sperm protein is blocked in the presence of SVF. There is no PKA enzyme activity in SVF. The presence of phosphate transfer activity between the sperm cell enzyme an… Show more
“…However, secretions from the seminal vesicles not only contribute to the fluid that serves as a vehicle for transporting sperm from the male to the female reproductive tract, but they also interact directly with the sperm cells [8]. Seminal vesicle fluid contains a number of factors that can influence sperm motility and viability [7,[9][10][11][12][13][14].…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
